Diversity and distribution of microbial communities on the surface of External ...
Viegas, Cristina A.; Borsoi, Giovanni; Moreira, Leonilde M.; Parracha, João L.; Nunes, Lina; Malanho, Sofia; Veiga, Rosário; Flores-Colen, InêsExternal Thermal Insulation Composite Systems (ETICS) are frequently used to enhance the energy efficiency of the built environment. However, stains of presumable biological nature are often detected shortly after application, causing cladding defacement and altering the building aesthetics. To address which microbiota could contribute to these biodeterioration related color/aesthetic anomalies, samples collect...
Discussão de estratégias para a avaliação da biocolonização em ETICS : um caso ...
Borsoi, Giovanni; Parracha, João Luís; de Cooman, Quinten; Flores-Coles, Inês; Viegas, Cristina A.; Nunes, Lina; Moreira, Leonilde M.; Veiga, RosárioConservar e Reabilitar monumentos, edifícios e espaços são oportunidades únicas para fomentar a sustentabilidade dos territórios, constituindo-se o ENCORE 2020 - 4º Encontro de Conservação e Reabilitação de Edifícios numa ocasião ímpar para discutir os desafios da transformação no espaço construído: otimizar recursos, reutilizar materiais, melhorar a eficiência energética, repensar as centralidades urbanas, pro...
Comparative analysis of transcriptomic responses to sub-lethal levels of six en...
Gil, Fátima N.; Gonçalves, Alina C.; Becker, Jörg D.; Viegas, Cristina A.Accidental spills and misuse of pesticides may lead to current and/or legacy environmental contamination and may pose concerns regarding possible risks towards non-target microbes and higher eukaryotes in ecosystems. The present study was aimed at comparing transcriptomic responses to effects of sub-lethal levels of six environmentally relevant pesticide active substances in the Saccharomyces cerevisiae eukaryo...
Evaluation of Arthrobacter aurescens Strain TC1 as Bioaugmentation Bacterium in...
Silva, Vera P.; Moreira-Santos, Matilde; Mateus, Carla; Teixeira, Tânia; Ribeiro, Rui; Viegas, Cristina A.In the last years the chloro-s-triazine active substance terbuthylazine has been increasingly used as an herbicide and may leave residues in the environment which can be of concern. The present study aimed at developing a bioaugmentation tool based on the soil bacterium Arthrobacter aurescens strain TC1 for the remediation of terbuthylazine contaminated soils and at examining its efficacy for both soil and aqua...
Potential Mechanisms Underlying Response to Effects of the Fungicide Pyrimethan...
Gil, Fátima N.; Becker, Jörg D.; Viegas, Cristina A.Pyrimethanil is a fungicide mostly applied in vineyards. When misused, residue levels detected in grape must or in the environment may be of concern. The present work aimed to analyze mechanisms underlying response to deleterious effects of pyrimethanil in the eukaryotic model Saccharomyces cerevisiae. Pyrimethanil concentration-dependent effects at phenotypic (inhibition of growth) and transcriptomic levels we...
Transcriptional profiling in Saccharomyces cerevisiae relevant for predicting a...
Gil, Fátima N.; Gonçalves, Alina C.; Jacinto, Maria João; Becker, Jörg D.; Viegas, Cristina A.Alachlor has been a commonly applied herbicide and is a substance of ecotoxicological concern. The present study aims to identify molecular biomarkers in the eukaryotic model Saccharomyces cerevisiae that can be used to predict potential cytotoxic effects of alachlor, while providing new mechanistic clues with possible relevance for experimentally less accessible eukaryotes. It focuses on genome-wide expression...

Cleanup of atrazine-contaminated soils: ecotoxicological study on the efficacy ...
Chelinho, Sónia; Moreira-Santos, Matilde; Lima, Débora; Silva, Cátia; Viana, Paula; André, Sandra; Lopes, Isabel M.; Ribeiro, Rui; Fialho, Arsénio M.Purpose To mitigate the environmental effects of atrazine, one of the cleanup strategies available is based on the use of atrazine-degrading bacteria. This work aimed to evaluate the efficacy of a previously developed bioremediation tool for atrazine-contaminated soils (combining bioaugmentation with Pseudomonas sp. ADP, hereafter designated as P. ADP, and biostimulation with citrate) on both soil habitat and r...
